I would say my favorite aromatic is regular plain old Captain Black original along with Lane's RLP-6, HGL, Sutliff #600 [Mixture-79 bulk], Gawith Hoggarth Brown Flake scented, Gawith Hoggarth Rum Flake, and Samuel Gawith 1792 Flake.
Sir Walter Raleigh Aromatic, most enduring aro in my lineup. I do like occasional dips into the vanilla world as well. I liked Mac Baren vanilla roll cake very well.
I have several. I really love a few Ashton ones. I like Gold Rush it's basically honey and lemon added to a bright VA. Reminds me of adding enough sugar to your tea to bring out the flavor profile but not make it taste super sweet. Their cross over in the green tin is amazing. EGR RIP. I love Captain Black Royal which prefer seven seas but oh well. C&D Founding Fathers is great. Simple straight forward but great. It's burly and Pomegrante but it's perfectly balanced.
I really like Danish aromatics from MacBaren like Va#1, Symphony and Golden Extra.
Like many English aromatics like stuff from G&H and SG.
As far as heavier aromatics I haven't really tried many, but I like MacBaren Black Ambrosia, Cult BRM, and a few others.
